Asynchronous retry for Future in Scala
import scala.concurrent.duration._
import scala.concurrent.ExecutionContext
import scala.concurrent.Future
import akka.pattern.after
import akka.actor.Scheduler
/**
* Given an operation that produces a T, returns a Future containing the result of T, unless an exception is thrown,
* in which case the operation will be retried after _delay_ time, if there are more possible retries, which is configured through
* the _retries_ parameter. If the operation does not succeed and there is no retries left, the resulting Future will contain the last failure.
